Used primarily as a photostabilizing agent in advanced polymer systems, especially in coatings and films exposed to prolonged UV radiation. Its unique structure allows it to absorb high-energy light and dissipate it as heat, preventing degradation of the polymer matrix. Commonly found in outdoor-grade plastics, automotive clear coats, and protective laminates where long-term weatherability is critical. Also investigated for use in specialty optical materials due to its ability to reduce photobleaching in sensitive dyes. Shows promise in improving the lifespan of organic photovoltaic devices by protecting active layers from sunlight-induced damage.
